5. Set environmental variables `export FLUFOR=gfortran` and `export FLUPRO=<path to where you unzipped the files>`. Note that the `FLUPRO` directory should contain __libflukahp.a__. Both of these variables will have to be set every time you open a new terminal.

+Also add an `-DWITH_FLUKA=ON` at the cmake command here if you want to use FLUKA as low-energy hadronic interaction model for the examples.
You can run the examples by using the binaries in `corsika-build-examples/bin/`.
